A Retrospective of Lo-Res Digital Art from Maker Faire NY

Quin's B&W Selfie Camera

I came across some slips of paper from Maker Faire New York this year which can best be desribed as ephemeral low resolution digital art. Above is a B&W selfie from the Qduino Mini Thermal Printer.

Hive76's ASCII Camera

The ASCII Art Camera from Hive76 used a small inkjet printer and a webcam.

Plinko Poetry

Plinko Poetry created poetry by detecting the path of a disc falling between pegs across scrolling headlines.

word.camera

The most extreme example of this art form I came across was the word.camera ITP project by Ross Goodwin which algorithmically generates a sort of novelette from a source picture.

word.camera uses convolutional neural networks (via Clarifai) to extract concept words from images. It expands those initial words (mostly nouns) into sentences and paragraphs using a lexical relationship database (ConceptNet) and a flexible template system.

The source picture for mine can be viewed on the word.camera site along with the full text. You can generate new ones by uploading a picture, but that is not nearly as satisfying as interacting with it in person. The physical project was housed in a vintage camera body with a small thermal printer, so that the camera itself was generating the art.

Accidental Glitch Art

The confluence of inexpensive electronics and relative ease of working with embedded systems that made all this art possible can also generate unexpected results. This last piece of accidental glitch art is from Quin’s project: while trying to print a picture, it encountered an error and gave me a printout of unintelligible characters interspersed with bits of picture.

Octolively derivative at ARMTechCon

Mouser display based on Octolively

We dropped by ARMTechCon last week to check out a tip sent in by email (thanks, Barry!) that Mouser Electronics was displaying something that looked like our Octolively modules.

Mouser staff had been inspired by an installation of our Interactive LED Panels to create something interactive that they could show off at Engineers Week at the Fort Worth Museum of Science and History. They used the Octolively as the basis for their project, and the kids loved it of course.

Blue "M" in LEDs

For trade shows, they built up a display with a mix of blue and white LEDs to show off the Mouser “M”. Based on the foot traffic it got while I was at the booth, it is quite popular.

ATmega164P

They made some minor changes from our original Octolively design and used different connector types to highlight Mouser’s product lines. The heart of the project is still the 40-pin DIP ATmega164P (perhaps anomalous at an ARM conference) running our Octolively code, which gave the Mouser folks a chance to play with some microcontroller programming.

It’s always exciting to see a derivative of one of our projects in the wild. Thanks to the Mouser folks for sharing their project story and sending the museum picture for us to share.

Inside the 741


Ken Shirriff has written an excellent exploration of the 741 op-amp, including decapping a metal can package AD741. There’s a very cool interactive viewer so that you can click on the components in the schematic or on the picture of the die to see what each one is and does.

…The 25pF capacitor in the 741 has a very small value but takes up a large fraction of the chip’s area. You can see the capacitor in the middle of the die photo; it is the largest structure on the chip. …

Our very own XL741 is referenced in the footnotes, too.
